GAS-SYRINGE WITH BRANGHED-OUT DISCHARGE-PIPE.

' Patented Jan. 2c, 1909.

Application filed January 26, 1907. Serial No. 354,2.

To all whom it may concer'nz' Be it known that I, KARL SCHMIDT, a merchant, and a subject of the German Emperor, and a resident of 9 Knesebeckstrasse, in the city of Neuruppin, Province of Mark, Kingdom of Prussia, and German Emfplire, have invented a certain new and 1 Gas-Syringe with Branched-Out Discharge-Pipe, of which the following is a specification. This invention has reference to an arrangement in gas syringes, the sprinkling nozzle of which is connected to the container for the liquid by rigid connecting means, and by the operation of which the til it is completely emptied, without any possibility of esca e of the gases,whichserve.for the GJGCtiOIl o the extin ishing liquid.

he arrangement formmg the sub ect matter of this invention resides in the act, that the dischar e pipe connected to the nozzle, is conducted to a valve chamber, from which two pipes extend. One of said pipes leads to the pointed end of the gas-syringe.- and the other pipe leads to the bottom. According to the position of the gas syrin e, whether the nozzle is directed upwards or ownwards, one or the other of said pipes is closed automatically by the valve provided in the so-that liquid can only be'forced trance opening of position;

The drawing) which occupies the lowest shows the subject matter of y way of example as an emvalve body, so

the interio'r'of the conical container a of the fire extin hing apparatus the dischar e pi e c whiiz h opens out into the chamber 65 an which is connected to the nozzle 6, is provided; This chamber is situated somewhat below the handle h of the apparatus and it is preferably of the shape of a cylinder with semi-spherical closin covers. To the chamber (1 the pipes e and f are connected. The pipe e is bent upon itself and leads to the bottom of the apparatus, while'the pipe.

of the liquid q+ he pipe 0 which leads off from the extinguisher with the nozzle situated above When the nozzle of the fire the horizontal. extinguisher is directed downwards, the valve body 9 drops down in e at its connecting point with the chamber, so that now only liquid through the pipe, j, which leads oft from the top of the apparatus can enter into the chamber (1 and thence it is forced into the discharge pipe 0.

It has been found 'to be of advantage to so arrange the axis of the chamber (1, that it position of the valve I the apparatus, can enter into the' the cylinder d-by its own weight and closes the opening of the pipe does notcoincide with the longitudinal I of the casing of the container, on the contrary chamber, so that.

M to impart the closing body 9 does not uncover the point of opening-out of the pipe f into the chamber d at too early a-moment.

found to .be' advantageous It has also been to have the pipes e and f projecta few millimeters into the chamber (1 and to grind the that it will fit unto the said projecting pipe ends, soas to be able to produce in an otherwise, well known mannera reliable tightening'in the terminal positions of the valve body, thereby preventing any escape of gases. 7 4 As will be evident from what has been said above, both .the sprinkling in a downward direction as Well as the sprinkling upwards is insured e ually'well by means of the arrangement of t e valve body in the chamber, connected to the discharge pipe. y What I claim and desire to secure by Letters Patent of the United States is 1. The combination, in a fire extinguisher,
